Fig. 8 is the circuit theory diagrams of signal coupling of the present invention
Fig. 4 is a transmitter circuit schematic diagram in the coupler of the present invention.
The present invention is further detailed explanation below in conjunction with accompanying drawing:
The non-local network of the present invention realizes that the method for telephone signal coupling is: this method must cooperate the touch-tone telephone of existing standard call function to realize, it is the call function that utilizes telephone set, carry out signal coupling transmitter from telephone handle and the receiver, mainly be coupled out bell signal, voice signal and busy-back signal, to realize the startup of additional recording or subset telephone, speech transmitted in both directions and three processes of end conversation on-hook.
When realizing this method, the handle 2 of primary standard phone is taken, coupler 1 is placed on the position of former telephone handle 2, as shown in Figure 1 and Figure 2, and the briquetting 5 that makes the operating mechanism on the coupler 1 is in above the hook switch of phone, then telephone handle 2 is placed on the coupler 1, make the receiver of phone be in the top that speech in the coupler 1 and busy tone detect induction coil L2, the transmitter on the handle 2 places on the transmitter of coupler 1.Bell signal induction coil L1 in the coupler 1 places on the ring Yang Sheng device of phone.Can realize the coupling of telephone signal.
The coupling of bell signal is after the magnetic-coupled mode of electricity consumption is picked up the magnetic leakage signal of ringing loudspeaker by ring detection induction coil L1, as shown in Figure 3, carrying out signal with computing amplification circuit I1 amplifies, capacitor C 1 through voltage doubling rectifing circuit, C2 and diode D1, D2 inputs to three plate pipe BG1 and carries out waveform shaping signal, input to Chip Microcomputer A then, Chip Microcomputer A is made up of central microprocessor CPU and memory and latch, by Chip Microcomputer A bell signal is relatively detected repeatedly, be confirmed to be bell signal, detecting the duration is one second, and be four seconds bell signal envelope break time.P1.2 end output control signal on the Chip Microcomputer A, this control signal can be transmitted into the signal of composite aircraft as required or start telecord, hook switch on the phone lifts in start-up operation mechanism 5 at once then, this operating mechanism can be electromagnet K, it also can be the briquetting 5 that the minitype motor driving reducing gear lifts operating mechanism, hook switch is risen, connect speech channel, set up talking state.In Fig. 1, foregoing circuit 4 is contained in the coupler 1.
The coupling of voice signal is to obtain the other side's calling signal by the magnetic leakage signal that speech in the coupler 1 and busy tone inductive coupling coil L2 pick up in the telephone handle receiver by the mode of electromagnetic coupled, as shown in Figure 3, by the transmitter in the coupler 14 (as loud speaker) recorded audio signals in the recording device is sent transmitter to handle, pass to the other side, as the speech of prerecording " principal and subordinate stays out; please leave word " etc., the sending of double-audio signal is similar to our speech and sends, as shown in Figure 3, coil L2 induced signal is after amplify, from a output the other side calling audio signal, under the program control in Chip Microcomputer A, can only detect the signal clocklike of ring and busy tone, the frequency of conversation signal is irregular.
The coupling of busy-back signal: behind end of conversation, the other side's on-hook, there is busy-back signal to send in the receiver of we's telephone handle, detect induction coil L2 by speech in the coupler 1 and busy tone and pick up the busy tone magnetic leakage signal, as shown in Figure 3, after computing amplification circuit I2 carries out the signal amplification, through capacitor C 3, C4 diode D3, after D4 voltage multiplying rectifier and triode BG2 carry out waveform shaping, input to Chip Microcomputer A and respectively be a kind of busy-back signal through relatively detecting interrupting time repeatedly, after busy tone continues the regular hour, Chip Microcomputer A output control signal control operation mechanism 5 starts, and depresses the hook switch on the phone, cut off speech channel, finish the one action circulation.
This method is owing to be to adopt the mode of electromagnetic induction to pick up ring, busy tone, voice signal, so for anti-interference, can take two kinds of measures, the one, with the large-scale space magnetic field of magnetic material bypass, the 2nd, on coil L1 and L2, adopt the series connection of two coil reversed polarity, it is opposite to go out bipolarity for the magnetic field induction of large space, the signal that amplitude equates offsets, for the useful signal leakage field, because magnetic field space is less, two parts induced signal polarity of coil is opposite, but differ in size, still have useful signal output after offseting, after handling like this, signal amplitude reduces to some extent, but anti-interference has obtained reliable assurance.
As shown in Figure 4, the transmitter 4 in the coupler 1 is from the b input we audio signal of giving orders or instructions, and can after amplifier I3 amplifies, be promoted loud speaker SP and send the transmitter that voice signal is sent into handle by acquisitions such as microphones.
